Best Windows 8 apps this week

Forty-second in a series. If you thought that last week's application growth was bad, you may be even more disappointed this week as it took another dive. Only 613 new apps were published this week, down another 117 apps from last week's weak performance.

The total app count rose to 79,130 apps this week, with 61,062 of them free to install and 18,068 commercial. Free apps grew by 537 apps this week and paid apps by only 76.

Microsoft announced the official release date of the Windows 8.1 update this week and confirmed once again that it will be free for existing Windows 8 users. The update launches officially on October 17 as a Windows Store update, and a day later as a preinstalled copy on new PCs.

World Conqueror 2 is one of several games that parent company EasyTech has released to store this week. All games share the same mechanics and are highly recommended if you are into strategy games.

The other games, just so you know their names, are European War 3 and World Conqueror 1945.

All three games are not free but reasonably priced at $2.99.

World Conqueror 2 ships with four campaigns of which you can play two right from the start, and the other two once you have completed the first ones. You can play the Axis from 1939 or the Allies from 1941 in World War 2. The two other campaigns let you play as Nato or Warsaw Pact.

Each campaign consists of multiple scenarios that you play through in chronological order. It is comparable to classics such as Panzer General or the more recent Panzer Corps game.

Most scenarios come down to conquering all enemy territories in as short of a time period as possible. Victory conditions award you with bonuses if you manage to achieve that in the given amount of days.

The battles are turn based. During your turn, you may hire new troops, use so called special cards to gain an advantage, move troops or attack the enemy.

Territories that you own provide you with resources that you need for the two first actions.

Once you have spent all your movements and resources, your allies move before the enemies start to do the same.

That is not all though, as you also have access to the conquest game mode which plays like a lighter version of many Paradox games.

World Conqueror 2 has a lot to offer for players who like strategy games. While it is not as complex as full priced games, it offers great value for the money.

Microsoft launched Power BI -- the BI stands for Business Intelligence -- back in July for Office 365 subscribers. It is basically designed to provide subscribers with options to view Office 365 reports on the web and via mobile devices.
